In science fiction, travels can be instantaneous or at least much faster than real - life. For example, in 'Star Wars', spaceships can make the jump to hyperspace and cover vast distances quickly. In real life, space travel is extremely slow. Also, in science fiction, travelers can often journey through time as well as space, like in 'Back to the Future', which is not possible in our current understanding of physics. Another difference is the variety of destinations. Science fiction can take us to alien planets with unimaginable environments, while real - life travels are mostly limited to Earth and our nearby celestial bodies.
Science - fiction animals often have unique physical features. For example, the Xenomorph has an exoskeleton which is very different from the soft skins or furs of most real animals. They also tend to have extreme abilities. Like the Sandworms in 'Dune' which can be incredibly large and move through the sand in a way no real - life animal can.
Fictional aircraft are frequently designed with a much greater emphasis on aesthetics. The Batwing in 'Batman' has a very sleek and cool design that is more about looking badass than practical aerodynamics. Real - life aircraft are designed mainly for efficiency and safety. Also, fictional aircraft can break the laws of physics more easily. The flying broomsticks in 'Harry Potter' like the Nimbus 2000 don't follow the same principles of lift and thrust as real airplanes. They operate based on magic, which is of course not a factor in real - life aviation. Moreover, fictional aircraft can often be customized to an extreme degree for the specific needs of the hero or the story, such as the X - Wing in 'Star Wars' which has been modified in different ways throughout the series.
Fictional spaceships are often much more advanced. For example, they can travel faster than light in many stories like in 'Star Wars' with the hyperdrive. Real - life spacecraft are limited by current technology and can't achieve such speeds. Also, fictional spaceships can be huge and have all kinds of amenities. Think of the USS Enterprise which has many decks and facilities for its crew. In contrast, real - life spacecraft are relatively small and cramped.
In science fiction, forests can have things that real - life forests don't. Like trees that are made of metal or can move on their own. Real - life forests are made of normal biological organisms, but in sci - fi, forests might be a mix of biological and mechanical elements.
In science fiction, melee weapons often have extraordinary abilities. For example, lightsabers can cut through blast doors, while real - world swords can't do that. Also, some science - fiction melee weapons are energy - based, like the energy blades in Halo, which don't exist in the real world.
Species in exotic science fiction often have abilities that are far beyond what real - life species possess. For example, some can fly without any visible means of propulsion, like the Moya crew in 'Farscape'. Real - life species are bound by the laws of nature we know, but in science fiction, these species can break those rules.
In science fiction, hospital beds can be highly advanced. For example, they may have the ability to levitate or move on their own, which is not a feature of real - life beds. Also, they could be made of some super - strong and lightweight materials that we don't currently use in real hospital beds.
In science fiction, names can be more unique and often carry symbolic meanings related to the story's themes. For example, a name like 'Zephyr' might be used to represent a character who is fast or free - spirited, while in real life, such a name is less common. Real - life names are often more traditional and based on cultural or family values.
Travel novels can inspire real - life travels by painting vivid pictures of far - off places. For instance, 'Eat, Pray, Love' made many people want to visit Italy for the food, India for the spiritual experiences, and Indonesia for the beautiful scenery. The descriptions of the destinations in the novels make them seem more appealing and real.
Science fiction demons can have technological aspects. They could be cybernetic entities with demonic programming or be created by advanced alien technology. This is very different from the traditional view of demons as purely spiritual or supernatural beings from hell. Also, in science fiction, the powers of demons might be more in line with scientific principles, like energy manipulation rather than just magic. For instance, a demon in a sci - fi story might be able to control electromagnetic fields, which is a more scientific - sounding power compared to the traditional ability to possess people at will.
